The CX-7 is a mid-size crossover SUV model from Mazda, the production version of the MX-Crossport concept car. The CX-7 is built in Hiroshima, Japan, starting in early 2007. The CX-7 was shown publicly for the first time at the 2006 Los Angeles Auto Show in January. Production officially began on February 20 at Mazda's Ujina#2 factory in Hiroshima. The CX-7 went on sale in spring 2006 as a 2007 model. It is also Mazda's first mid-size SUV since the Navajo was discontinued in 1994. Though outwardly similar, the CX-7 and the Mazda CX-9 do not share platforms. The CX-7 shares the front suspension of the Mazda MPV minivan and the rear suspension from the Mazda5. It shares its turbocharged inline-4 engine with the Mazdaspeed6 and uses a 6-speed automatic transmission. Sales of the CX-7 were mediocre, as it slotted between the sizes of compact and midsize crossovers, so it was not competitive in either category, plus the turbocharged model had poor fuel economy. The 2012 model year will be the last year for the CX-7 to make way for the release of the CX-5. The CX-5 has a more efficient powertrain and more interior room, while its exterior is smaller than the CX-7.
